Hello everyone, I have a question: what is the system idling of a Century engine with carburetor Villiers?
I ask because it seems to me that my engine LLS has the least a little high. maybe it's just me ...

The idling speed can be adjusted with the adjuster on the top of the carb

Slide the cover up and slacken the locknut:

Adjust the speed to what you require with the knurled adjuster:

re-tighten the locknut and slide the cover back into position.

Shows what I know, I thought it was to take the play out of the cable.

If this is how you adjust the tick over, how do you stop the motor?

You can adjust the above so that when the throttle control is turned to its minimum position the engine stops.. That can be a nuisance

You can adjust it so that it continues to idle. That is Ok if you have a clutch. You then stop the engine by turning off the fuel and waiting until it runs out of fuel.

If you don't have a clutch you can try to judge when to turn off the fuel so that the engine stops at the right moment. You might end up rowing few yards, or you might crunch the boat onto the slipway, if you misjudge it.

BUT the clever thing to do is adjust the idle speed so that it continues to idle while the tiller is kept horizontal but stops if the tiller is lowered.

It wont do that you cry ... But it will, and that is how I adjust the Featherweight I use on my tender.

Only Seagulls with a CDI & a stop button have the provision to have a proper "tickover" !

The vast majority i.e. all the rest, "tickover" is found by delicate use of the throttle lever.

All to their own, My FVP has a short fixed tiller and I get to rub my sleeve on the fly wheel from time to time.
I would rather catch a pullcord or my sleeve in the starter pulley knowing that I could turn it off and not wait until the fuel runs out.

Hospital is also a nuisance.

I've often wondered about fitting a stop button. ( mines a Wipac ignition) It should only be necessary to wire a push button across the points. I was wondering if it would be possible to mount it through the base plate.

I'm a newbie here with no real knowledge of engines. I stop my featherweight by putting my
hand over the air intake. Am I doing something wrong, or is it ok to do that? :|

Each to their own.
But like I saw on a seagull outing, a seagull, nicely polished and running very well indeed, even though the operator had the tiller handle in both hands, and he needed too, because the motor had detached from the transom and was merrily skipping its prop across the bow of the boat.

Putting a hand over the air intake wouldn't be an option, but that's what the thumb control is there for.

The proper way to stop the magority of Seagulls is to shut the throttle.

You get canny though and experts turn the fuel off so they coast the last 3 yards to the beach!

2 Strokes like the Seagull never tick over like a 4 stroke. Though I once heard a Vespa that sounded like a clock on tickover, regular and steady. 2 strokes do not properly 2 stroke till the revs come up a tad! (My 1958 Bantam is the same, and you close the throttle to stop that too!)
